Description

Technical Field

[0001] The invention relates to the technical field of machining and heat treatment, and in particular to a novel mobile turnover vehicle suitable for the turnover of machining and heat treatment production lines. Background Art

[0002] Heat treatment is the process of heating, keeping warm and cooling metal materials to improve their physical, chemical and mechanical properties. Heat treatment includes quenching, tempering, annealing and other treatment methods; machining is the process of cutting, drilling, reaming, tapping, grinding and other processing of metal materials to form parts of specific shapes and sizes, such as shafts, gears, threads, etc.

[0003] Heat treatment and machining are inseparable in the manufacturing industry and often need to be used in conjunction to meet the requirements of parts. The impact of heat treatment on machining: During the machining process, the hardness and toughness of the material are crucial. Heat treatment is often used to increase the hardness and toughness of the material and reduce fragility and stress, making it easier to machine. For example, parts that require high strength under extreme conditions can be hardened and tempered to increase their hardness and toughness, thereby extending the service life of the parts. The impact of machining on heat treatment: During the machining process, the material usually deforms and produces residual stress, which can adversely affect the performance of the parts. Heat treatment can help remove residual stress, improve material organization, and optimize part performance, thereby improving its quality and reliability; After searching, the application with patent publication number 212861514U discloses a heat treatment tooling turnover material cart, including a frame, four casters symmetrically installed at the bottom of the frame, a hook mechanism installed on one side of the frame, the hook mechanism connected to the brake mechanism, the hook mechanism includes a hook, a connecting rod, and a handle, a rotating shaft is installed on the frame through an axle support plate, a plurality of hooks are evenly spaced and fixed on the rotating shaft, a torsion spring is set between two hooks on the rotating shaft, one end of the rotating shaft is connected to the output end of the connecting rod mechanism, and a handle is connected and installed at the input end of the connecting rod mechanism. The utility model cleverly combines the heat treatment tooling with the turnover material cart, which can directly transfer the entire material to the heat treatment production line, and can also directly transfer the heat treatment tooling from the heat treatment production line to the trolley, reducing the two manual loading processes, simple operation, and improving work efficiency, while avoiding the risk of bumps during loading and unloading; At present, materials between machining and heat treatment processes are often transported by crane or forklift (electric or fuel) due to the complexity, diversity and heavy weight of the products. The process often requires manual operation, which is inefficient. Sometimes accidents may occur during operation, such as improper crane hoisting or forklift hitting people or objects.
